Hydrophilic non-woven fabricIt can be seen from the literal meaning of the hydrophobic non-woven fabric is the opposite. Because fibers or non-woven fabrics are high-molecular polymers, they have fewer or no hydrophilic groups, and cannot obtain the hydrophilicity required for non-woven fabric applications. Adding a hydrophilic agent to the fiber during the fiber production process, or adding a hydrophilic agent to the fiber during the fiber production process, the non-woven fabric produced in this way is the legendary hydrophilic non-woven fabric.
Some people may not know much about hydrophilic agents. In fact, the hydrophilic agent can quickly reduce the surface tension. Most of them are long-chain organic compounds, and there are both hydrophilic and lipophilic groups in the molecule.
1, Types of surfactants: ionic surfactants and non-ionic surfactants.
2, Non-ionic surfactants: Polysorbate (Tween)-20, -40, 60, 80, sorbitan monolaurate (Span)-20, 40, 60, 80, polyoxygen Ethylene lauryl ether (Myrj)-45, 52, 30, 35, emulsifier OP (nonyl phenol polyoxyethylene ether condensate), Lumbrain A (polyoxyethylene fatty alcohol ether), etc.
3, Anionic surfactants: soft soap (potassium soap), hard soap (sodium soap), aluminum monostearate, calcium stearate, triethanolamine oleate, sodium lauryl sulfate, sodium cetearyl sulfate, sulfated castor Sesame oil, sodium dioctyl succinate, etc.
4, Cationic surfactants: Zeolite, new Zeolite, benzalkonium chloride, etc., almost all disinfectants.
5, Amphoteric surfactants: less, and all are disinfectant and antiseptic.
This kind ofHydrophilic non-woven fabricIt is made of ordinary polypropylene spunbond non-woven fabric through hydrophilic treatment, which has good hydrophilicity and permeability. Mainly used in sanitary products, such as diapers, paper diapers, and the surface layer of sanitary napkins, which can quickly penetrate to keep dry and comfortable. It can be said that applications are very common in our lives? If you want to know about hydrophilic nonwovens, come to Kangtai Nonwovens Co., Ltd.!
